Let's say that you do not get all of your syrup through your filter press. You add new syrup from your evaporator to the old syrup with DE in it that did not go through. Then you finish the entire batch and test with a hydrometer. Can you trust the hydrometer reading because the batch contains DE? Has the DE altered the density and thus the reading on the hydrometer? In this scenario we have 2-3 gallons of DE syrup mixed in to get a total batch of 7 to 8 gallons.
I do not believe that the DE will affect the density of the syrup or your hydrometer reading.
the De should be caught in the filter media unless you have a hole. So the syrup would not have DE in it or at least very very little. Does anyone with more knowledge know for sure
I don't have any data, but my experience is the same -- never seen DE get through the papers.Quote:

If it was not stirred up, then I surely would not have an effect. In suspension, if it did effect it, I dont think it would be enough to warrant concern.
DE has no effect on the syrup density as long as it didn't pass through to the finished syrup.
I don't know, BUT I have always checked density before adding DE and/or after filtering, not when the DE is blended in.
In my experience, DE does affect the density. It makes your reading on the hydrometer read heavy(therefore your syrup will end up light). I never add DE until after the batch is adjusted perfectly.

Testing with a hydrometer measures the dissolved solids in the syrup. DE or niter should not affect the reading, as they are not dissolved. (Think about throwing some marbles into the syrup). However, in my experience, some digital refractometers are not accurate measuring syrup that has sediment (niter or DE) in it.
